MISSION AND ORGANIZATION
The primary mission of Chanute Air Force Base is to pro-
vide formal technical training for both officers and airmen of
the United States Air Force in the fields of weather, special-
ized aircraft mechanics, aircraft maintenance and certain trade
or craftsman courses such as sheet metal, weiding, machinist,
woodworking, etc. In addition to Air Force personnel, officers
and men from other branches of our Armed Services as well as
foreign students are selected to attend courses in the Technical
In order to carry out this mission under the Wing-Base pat-
tern of organization, direct supervision over the operation of
the Technical School is vested in the Primary Mission Group or
the 3345th Technical Training Group.
For administrative efficiency in the operation of the school
and the conduct of the various courses required, the school is
organized into five (5) departments, each one of which will be
discussed later in this booklet followed by a brief account of
the courses conducted.
For administrative control over personnel, including stu-
dents, staff and instructors, the Group is organized into a
Headquarters Squadron, five (5) Instructor Squadrons and fifteen
(15) Student Squadrons to provide for the maximum student load.
Insofar as practicable, students are assigned to squadrons
homogeneous to the courses being pursued. The student's status
and progress in school is monitored at the squadron level to pro-
vide for the maximum guidance and counseling to enable him to
successfully complete his course.
In the last analysis, the true test of whether or not the
Technical School is accomplishing its mission is determined by
the calibre of its product - our graduates - and how well they
perform in the field.
Chanute graduates of the past have established high standards
of technical proficiency and good maintenance. For the future
there is great pride and confidence that these traditions of past
performance will be maintained without fail.
CHANUTE AIR FORCE BASE IN RETROSPECT
Chanute Air Force Base, home of the oldest and one of the
leading Technical Schools in the Air Force, was established in
1917 to train pilots for World War I. July 18, 1917 marks the
date when a dozen Curtis "Jennies" with an instructor and stu-
dent in each took off as the first class of formal instruction
at this station.
In 1921 the "Army Enlisted Mechanic School" was establish-
ed at Chanute when mechanic and technician courses were transfer-
red from Kelly Field, Texas. During the following year (1922),
the Photography School at Langley Field, Virginia and the Air Ser-
vice Communications School, Ft. Sill, Oklahoma, were added to the
Technical Training Program at this base. Thus, we see that the
original school embraced the fields of mechanics, photography,
communications and armament.
In 1924 a clerical school was added to the curricula, but
this activity along with photographic and armament training were
transferred to Lowry Field, Colorado in 1938.
1938 marked the beginning of the expansion program when an
appropriation of eight and one-half million dollars ($8,500,000.
00) was made for the construction of modern facilities. Build-
ings constructed as a result of this appropriation include all
the centrally located brick living quarters, a modern hospital,
a test blocks building, and the three large hangars. The follow-
ing year another appropriation was made for the construction of
an additional hangar which is now designated as hangar #3 and is
somewhat smaller than the original three.
The peak period for the training of personnel in technical
skills was reached during the war years (1940 - 1945) when over
200,000 men were graduated from the various courses.
Since the termination of the war and up to date, the school
has passed through the post war era with a student load averaging
around 3000 students enrolled in over forty different courses,
reaching an all time high for peace time with over 5000 students
in school under the expanded program of 1949 and 1950.
Since the origin of technical training at this base in 1921,
many changes have taken place both in the scope of courses offered
and concept of training to meet ever changing demands and require-
ments of the Air Force. This school has every reason to be proud
of the contribution it has made and the vital part it has played
in the development of the United States Air Force.

CRANUTE AFB TECHNICAL COURSES
A total of approximately forty-five (45) courses (including
special training and reserve force courses) are offered at this
base. These courses are grouped, insofar as possible, into their
respective occupational areas and each group assigned to one of
five (5) major school departments for administrative purposes.
These school departments are listed below along with the courses
given within each department. It may be noted that throughout
the written and pictorial descriptions of the individual courses
of instruction, no attempt has been made to describe each of the
very similar courses; instead, one general description is given
to cover each of such groups. As an example: one general descrip-
tion is included to depict technical instruction given in all of
approximately nine (9) power plant mechanic courses.

THE USE OF EQUIPMENT IN TRAINING
Throughout the foregoing section (Chanute AFE Technical
Courses), it may be noted that the illustrations depicting in-
structional situations in the various courses show a wide variety
of equipment used in many different ways. Some of the more fre-
quent uses to which aircraft equipment is put are as:
Cut-aways to show internal construction.
Items for disassembly and assembly purposes.
Equipment for use in bench testing.
Items for removal and installation practice.
Assemblies of equipment and parts to comprise working
replicas (trainers) of airplane systems.
As a further explanation of the uses to which trainers are
put, a general discussion of the following is included:
The Need for Trainers: In most instances the development of
a trainer is brought about by the need of the classroom instructor
for an aid in the teaching of some airplane system.
Types of Trainers: Trainers are prepared to show the equip-
ment employed in a particular airplane system, to include common
troubles for diagnosis" and correction, and as complete operating
Common Trainer Systems: When new types of aircraft are manu-
factured, trainers are usually prepared to give technical instruc-
Hydraulic systems (may be one or several systems) .
Oxygen systems (when they are different from ordinary types)
Fire extinguishing systems.
Assist take-off systems.
Heating, ventilating and pressurizing systems.
New and different features such as:
Auto dive brakes.
Pilot ejection seat.
Engine cutaways and exploded models.
Size of Trainers: Trainers may vary in size from quite small
up to large wheel or caster mounted items approximately 6 feet in
height, up to 8 feet in length in any one detachable section, and
in the vicinity of 4 feet in width. These dimensions cannot be ex-
ceeded since all trainers must be of a size to move through regular
doorways and to be transportable by air.
Number of Trainers Employed: There are approximately 1550 train-
ers in use throughout the schools of this base. Of this number, 1400
were manufactured in the Training Aids Section of this school and 150
are standard trainers.
